DETAILED DESCRIPTION

The programmatic advertising systems, methods, and computer program products described herein provide a modern solution to in app monetization using a highly optimized server to server (S2S) real time bidding (RTB) solution. The current monetization ecosystem focuses heavily on the desktop world. That is, it focuses heavily on websites. Advertisers often do not understand the difference between the two mediums. As a result, ads that are normally displayed in the desktop world get recycled and reused within mobile environments. This creates a suboptimal environment for the advertiser, publisher, and users alike.

In the desktop world, ads may be referred to as tags. Tags are characteristically snippets of JavaScript that a publisher can copy and paste into hypertext markup language (HTML). These tags make cross-site network calls to communicate with demand side providers (DSPs) and supply side providers (SSPs) in order to sell ads on a website. This flow may not work well within certain environments, including mobile environments.

As a result, various methods may be used to help advertisers bridge the gap between other platform (e.g., mobile) monetization and desktop. These methods include mobile software development kits (SDKs) used to bridge the communication gap between DSPs/SSPs and publishers. The SDKs allow mobile publishers to quickly monetize their apps with advertisements while adding SDK bloat (increased app sizes), latency, and a buyer-side bias.

However, one issue with an SDK solution is that it is not transparent to the publisher how their app is being monetized. The SDK solution may also have the same inefficiencies as the desktop world. These inefficiencies may be due to the waterfall setup that advertisers, DSPs, and SSPs may be accustomed to working with.

In various embodiments, the systems described herein relate to an efficient ad server that uses server to server connections with DSPs and SSPs to perform blind, real time bidding auctions across multiple creative types. In various embodiments, a lightweight SDK may be used to interface with the ad server disclosed herein. In various embodiments, no SDK is necessary to interface with the ad server disclosed herein. As a result, the systems disclosed herein create a fair and fast auction that brings both transparency to the publisher and increases overall revenue.

In various embodiments, hardware may be used in hosting the auction within a cloud infrastructure. In various embodiments, the code may be written with concurrent functions and latency may be reduced. In various embodiments, latency may be measured in milliseconds. In various embodiments, by allowing mobile applications to access the ad server without an SDK or with a lightweight SDK, application sizes are not significantly impacted (e.g., not increased). In various embodiments, integrating a demand source for a publisher does not require an update to the app, as all integrations are handled on the backend.

In various embodiments, if a lightweight SDK is used, the client device SDK may include a requesting and rendering component, which can be used independently from one another that allows a publisher to make a request to the ad server to sell ad-space inventory and on a winning bid, render the ad from the returned markup. In various embodiments, a publisher can use the requesting component to only generate requests to the ad server but render the ad markup using an implementation of their choosing if it supports the open standards defined by the interactive advertising bureau (IAB) (e.g., MRAID, VAST, VPAID, etc.) or the publisher can generate requests to the ad server using their own implementation on the client or server side but render the ad markup using the rendering component of the SDK. In various embodiments, usage of the SDK regardless of which components are included may require that the component be initialized during application startup by providing a publisher key and API key as parameters to an initialize function.

In various embodiments, the requesting component of the SDK generates requests to the ad server for ad-space inventory using unrestricted device information such as the make, model, and manufacturer of the device, the device's web-browser user agent string, the type of physical network connection (4G, 3G, wifi, etc.), and the system-provided advertising ID that is linked to the current user of the device. In various embodiments, the requesting component may also include details provided by the publisher about the mobile application, the SDK implemented in the app, and/or information about the user of the app. In various embodiments, user information can include the location, gender, age, year of birth, and keywords describing the user. In various embodiments, the publisher can inform the SDK if the user is subject to regulations such as CCPA or GDPR and include information related to those regulations that will be passed in each request to the ad server from the SDK. In various embodiments, users of the requesting component generate requests using a class, which may be an implementation of the OpenRTB specification. In various embodiments, the class may provide helper methods to fill inventory for banner ads, video ads, or a hybrid interstitial that can fill a banner or video ad in the provided ad-space. In various embodiments, an object may be passed to a request manager function to fill in the remaining device, user, and app details and finally send the request to the ad server to start an auction. In various embodiments, a winning auction will return a response which contains information about the buyer of the ad such as the demand source and winning bid price, as well as the type of ad (banner or video) and the markup to render the ad.

In various embodiments, the rendering component of the SDK provides a plugin architecture that allows the publisher to customize the rendering of different ad markups. In various embodiments, the SDK includes renderers for static (Banner/WebView display) and video ad markup. In various embodiments, the static renderer of the SDK may rely on the client device's implementation (e.g., of WebView) that is capable of rendering HTML markup and is augmented with the SDK implementation of a specification (e.g., MRAID 3.0) that allows an ad access to some native features of the device to enhance the experience for the end user. In various embodiments, the video renderer may use a publicly available SDK to parse a response containing VAST extendable markup language (XML) and handles the creation of the native video player for the ad as well as reporting tracking and conversion events back to the ad server and demand partners. In various embodiments, renderers can be added or replaced in the client SDK by implementing the renderer interface and installing the implementation for an ad type. For example, a custom video renderer could replace the default renderer provided by the SDK or a renderer for a new type such as a social network's native ads can also be installed. In various embodiments, all Renderers may provide an implementation of an ad controller interface defined in the SDK, which provides a single API for interacting with all the different ad types, allowing the publisher to reuse the same implementation logic to display an ad regardless if it is a video ad which can start and stop playback or a banner ad that display a static image.

In various embodiments, in a full client-side implementation, the requesting and rendering components may be combined with an ad manager class. This class serves as a bridge between the components by providing all of the relevant methods to set details global to all requests as well as make the requests themselves and handle the response by sending it to any installed renderers. In various embodiments, the method to request and render an ad is called may accept as its parameters a request object and a container to render the ad inside. In various embodiments, the client SDK may provide extensions for including third party SDK-based demand. In various embodiments, the third-party SDKs may be included by the publisher in its app and subsequently registered with the ad server SDK.

FIG. 1 shows an exemplary waterfall solution 100 for cross-network calls to communicate between DSPs and SSPs, showing both the bid floor and the sequential flow of the system. Waterfall solutions, like that shown in FIG. 1, are like a daisy chain, where one ad call falls back to the other. Likewise, in order to integrate new demand, source publishers would also have to install the SDK of each demand source in the waterfall, which drastically increases the app's overall size.

Using what are called “floors” a publisher controls what they suspect a DSP or SSP will pay to sell an ad. This system is both slow, introduces a lot of human error, and adds management costs. It requires a system to make N sequential network calls to buyers to see if the buyer wants to sell an ad for the asking price or floor, which increases latency. It also requires that a publisher has a programmatic ads manager to set those floors, monitor the floors, and change the configuration of the waterfall.

Additionally it removes overall control from the publisher on how their audiences are monetized. The buyer at the top of the chain controls the programmatic ad stack. This flow always favors the DSP or SSP. That is because the DSP or SSP that is at the top gets to cherry pick who they want to buy on. The second issue is that the ad is never sold at market value. That is to say that DSP or SSP can sell an ad for an unreasonably low price because they are not competing against each other. Lastly, each network call is done sequentially, which adds latency. The longer it takes to show a user an ad the less likely that ad will be seen. That is bad for DSPs/SSPs, advertisers, and publishers alike.

Methods using mobile SDKs may allow publishers to install an SDK to quickly monetize their audiences. FIG. 2 illustrates a header bidding system 200, showing all the highest bidder winning the auction regardless of order. A header bidding system 200 mitigates some of the issues around latency because all DSPs and SSPs are asked concurrently to bid. However, the header bidding system 200 still relies heavily on legacy tag based integrations. This means that floors still have to be managed across multiple DSPs and SSPs.

FIG. 3 illustrates an exemplary flow diagram of a header bidding system 300. In header bidding as shown in FIG. 3, the client 302 may be a mobile device. The mobile device may have limited internet speed. At 311, the client 302 makes a predetermined number of network calls to two or more demand sources 306 a-306 c. At 312, the two or more demand sources 306 a-306 c perform any necessary actions (e.g., auctions) on their respective servers. At 313, each of the demand sources 306 a-306 c then submit a bid value and, in some embodiments, a creative to the client 302. It is not always the case that a creative will be sent back at 313 and, in some embodiments, a secondary network call is made by the client 302 to fetch the creative from one or more of the demand sources 306 a-306 c. At 314, the client 302 sorts through the bid responses that came back before the client timeouts (often many seconds later) are met. At 315, the client 302 attempts to render the asset.

FIG. 4 illustrates an exemplary flow diagram 400 of a programmatic advertising system according to an embodiment of the present disclosure. In various embodiments, the advertising system 400 is unlike waterfall solutions and solves issues that come with a waterfall bidding system, such as latency, yield, transparency, fairness, and efficiency. In various embodiments, the advertising system runs a (real-time bidding) RTB auction on the behalf of publishers. In various embodiments, the advertising system 300 does not require or use a software development kit (SDK) to run these auctions. In various embodiments, SDKs allow publishers to quickly monetize their apps, but may introduce latency and may be inherently opaque. In various embodiments, because the advertising system 400 holds the auction on a backend service (e.g., remote machines living on a cloud infrastructure), it is not subject to the same network latencies as a SDK. In various embodiments, where an SDK is used, the SDK may require the use of the mobile device's network speed, e.g., WIFI, 4g, 3g. In various embodiments, network speed may be highly variable for certain mobile devices, which means that SDKs may not be able to perform or guarantee constant high performance. In various embodiments, highly concurrent network calls being made on a mobile device in the case of the SDK bidding solutions suffer from the same inadequacies. In various embodiments, SDKs may require the use of the hardware of the device on which the code resides. In various embodiments, some handheld mobile devices may not contain hardware sufficient to run high performance and concurrent auctions. In various embodiments, the advertising system 400 may remove the cost of latency, which increases DSPs/SSPs, advertisers, and publishers overall yield.

In various embodiments, the advertising system 400 as an ad server is fully transparent. In various embodiments, because the advertising system 400 does not have its own demand, auctions may be operated fairly among bidders. In various embodiments, the advertising system 400 does not give priority to any single DSP or SSP. In various embodiments, the advertising system 400 does not use a tag-based system. In various embodiments, floors may not be required to be managed. In various embodiments, the advertising system 400 may use the RTB protocol to conduct auctions. Additional information on the RTB protocol is available in the OpenRTB API Specification Version 2.5, IAB Technology Laboratory 2016. In various embodiments, each DSP and SSP bids in a blind auction. Buyers are forced to pay what is closer to market value for the inventory instead of relying on the tag based or waterfall buyer favored implementation. This increases publisher side yield.

In various embodiments, the advertising system 400 may optimize the auction process in ways no other system does. Many systems used tag based implementations to determine the creative type. An auction or waterfall solution can typically only return one type of creative, such as, for example, either a static/banner ad type or a video ad type. In various embodiments, if a publisher can display either creative in the same placement location, the publisher may be forced to choose between both creative types (i.e., banner or video) or request for each creative separately, which may increase latency and decreases yield. In various embodiments, the advertising system 400 runs a multiple creative single call auction. In various embodiments, the advertising system 400 may return the highest paying valid ad to the publisher, which increases yield and performance.

In various embodiments, the advertising system 400 includes two interfaces: Auctionable and Demand. In various embodiments, Auctionable defines the behavior around requesting the bids from each demand source, retrieving the ad markup from the winning demand source, and logging the demand sources canonical name. In various embodiments, Demand defines the behavior each demand source must implement to satisfy requirements around its ads and their creative types. It also defines how the advertising system 400 communicates with the DSP or SSP.

In various embodiments, a client 402 requests that an advertising system 404 starts an auction. The client 402 communicates to the advertising system 404 via an HTTPS POST request, where the body of the request is an extended 2.5 RTB object. Because each demand source's implementation is very different from each other, the advertising system 404 de-normalizes the received RTB object and sends the information concurrently downstream to each DSP and SSP 406 in the manner that those systems understand. For each auction, a timeout is set by the publisher. If no timeout is set, then the advertising system 404 defaults to a default value, e.g., 500 ms. If a demand source takes longer than the timeout, the Transmission Control Protocol (TCP) connection is closed immediately and that demand source's bid is no longer valid. After receiving all the bids within the set timeout, the advertising system 404 normalizes that information and sorts the bids by highest effective cost per thousand impressions (ECPM). Each bid in the array is then iterated on to check for validity or in some cases to fetch the creative's markup. If the bid has the highest ECPM and is valid, regardless of creative type, that ad is served back to the client.

In various embodiments, the advertising system 404 may determine if a Static/HTML/Banner ad is valid. In various embodiments, the markup may be valid HTML. In various embodiments, determining the validity of a video ad (VAST XML) may involve checking that the mime types the publisher requested are present. In various embodiments, the advertising system 404 checks that the VAST XML has been implemented properly. It is often the case that human error causes the VAST XML to be incorrect, which causes the video to not be rendered on the publisher's app. This leads to revenue loss for the publisher, DSPs/SSPs, and advertisers alike. As a result, the advertising system 404 mitigates the risk of running video ads by validating the creative before sending it to the client to render.

In various embodiments, the advertising system 404 may provide Multi-Creative Auctions. In various embodiments, the extended RTB 2.5 object that the advertising system 404 requires the client send, allows for the request.imp object to contain multiple creative formats within a single request. For instance, a request.imp object containing both the banner object and the video object tells the advertising system 404 that the publishers wishes to trigger an auction where Static/HTML/Banner ads are competing against video VAST XML ads. This increases the publisher's fill while also increasing the overall ECPM. All other systems segregate creative types, while the advertising system 404 optimizes by allowing all creative types to compete in a single unified auction at the publisher's discretion.

FIG. 5 illustrates an exemplary flow diagram 500 of a programmatic advertising system according to an embodiment of the present disclosure. In FIG. 5, the client device (e.g., mobile device) 502 may have an internet speed that is limited to a predetermined speed. In various embodiments, at 511, the client device 502 makes a request (e.g., a call) to ad server 504. In various embodiments, the request may be a single request. In various embodiments, at 512, the ad server 504 makes network calls to two or more demand sources 506 a-506 c. In various embodiments, the two or more demand sources may be DSPs. In various embodiments, the two or more demand sources may be SSPs. In various embodiments, the two or more demand sources may be exchanges. In various embodiments, the two or more demand sources may include a remote server. In various embodiments, at 513, each of the two or more demand sources 506 a-506 c then perform any necessary auctions on their side to determine a bid and creative to present to the ad server 504. In various embodiments, at 513, the demand sources 506 a-506 c submit a bid value and, optionally, a creative to the client. In various embodiments, a secondary network call is made to fetch the creative from the corresponding demand source 506 a-506 c. In various embodiments, at 514, the ad server 504 sorts the bids and/or corresponding assets. In various embodiments, at 514, the ad server 504 unwraps the asset(s). In various embodiments, at 514, the ad server 504 validates the assets from the bid responses. In various embodiments, at 514, the ad server 504 validates the returned assets before a predetermined timeout (e.g., 500 ms). In various embodiments, at 515, the ad server 504 returns the asset back to the client device 502 for rendering. In various embodiments, at 516, the client device 502 renders the asset for the user.

In various embodiments, the request includes an indication of advertising inventory for sale. For example, the request may indicate one or more static (e.g., banner) ads and/or one or more video ads that are for sale. In various embodiments, the request may include make, model, and manufacturer of the client device. In various embodiments, the request may include a user agent string of the client device. In various embodiments, the request may include information regarding a network connection of the client device. For example, the request may indicate network type, such as, for example, wifi, 5G, 4G, 3G, etc. and/or speed of the network. In various embodiments, the request may include an advertising identification linked to a current user of the client device. In various embodiments, the request may include user information (e.g., location, gender, age, birth year, and keywords describing the user). In various embodiments, the ad server may fill in details into the original request thereby generating a modified request. In various embodiments, the details filled-in may be unsupplied information.

In various embodiments, the asset received at the ad server with the winning bid may be unwrapped. In various embodiments, text data of the asset may be parsed. In various embodiments, one or more URLs may be removed from the text data. In various embodiments, the removed URL(s) may point to other video ad servicing templates (VAST). In various embodiments, unwrapping is performed until a URL pointing to the asset is identified. In various embodiments, the URL pointing to the asset comprises a content delivery network (CDN) address.

In various embodiments, the fully unwrapped asset may be validated against requirements of the client device. For example, if the client device can only render one type of video, then only that type of video should be passed along to the client device. In various embodiments, validating the asset comprises determining whether the CDN address comprises an accessible creative. For example, the ad server may access the link to determine that the link is valid. In various embodiments, the ad server may receive all or a portion of the advertisement from the source. In various embodiments, the ad server may use all or a portion of the advertisement in determining whether the advertisement is valid for the particular client device. In various embodiments, validating the asset comprises determining whether the CDN address comprises a creative having a content type capable of being presented on the client device. In various embodiments, validating the asset comprises determining whether a labelled content type matches a true content type of the creative. In various embodiments, validating the asset comprises determining whether the CDN address comprises a creative having a bit rate capable of being presented on the client device. In various embodiments, validating the asset is performed in less than or equal to a predetermined amount of time (e.g., 20 ms).

FIG. 6A-6D illustrates a process for unwrapping an asset according to an embodiment of the present disclosure. FIG. 6A shows a wrapped asset including Video Ad Serving Template (VAST) code (e.g., XML) that is provided to an ad server of the present disclosure. In FIG. 6A, a first VAST ad tag URI is removed. FIG. 6B-6C show further unwrapping steps where all trackers and/or metadata are unwrapped (i.e., removed) and stored for later use (e.g., insertion back into the fully unwrapped document). In FIG. 6B, a second VAST ad tag URI is removed. In FIG. 6C, a third VAST ad tag URI is removed. In various embodiments, this step may be performed by calling a function (e.g., VastAdTagURL). In various embodiments, the unwrapping process may be repeated up to a predetermined limit of times. In various embodiments, the unwrapping process may be performed anywhere from one to up to any suitable number (e.g., ten) times. FIG. 6D shows a fully unwrapped asset that points to a media file (i.e., the advertisement to be rendered). In various embodiments, the fully unwrapped asset may include a URL pointing to the advertisement to be shown. In various embodiments, the fully unwrapped asset may include an identification number. In various embodiments, the fully unwrapped asset may include one or more tracking events.

In various embodiments, as shown in FIG. 6D, the asset is now inline and all media assets may be retrieved from the XML, e.g., the MediaFiles Object. In various embodiments, the fully unwrapped asset includes one or more URLs pointing to media files to be rendered. In various embodiments, the media file(s) may include any suitable video file type (e.g., mp4). In various embodiments, the media file(s) may include any suitable static image type, including compressed or lossless types (e.g., png, jpg, tiff, etc.). In various embodiments, the bit rate of the media file(s) may be checked to confirm that the bit rate is within bounds of a publisher's request. In various embodiments, if the bit rate is out of bounds (e.g., too high or too low), the asset is labeled as noncompliant. In various embodiments, the ad server may confirm whether the file type is within accepted parameters (e.g., Mime-Types) set by the publisher. In various embodiments, the ad server may perform concurrent network calls to the server (e.g., CDN) hosting the advertisement. In various embodiments, if the server hosting the advertisement is down and/or slow (e.g., times out), the ad server may mark the asset as noncompliant. In various embodiments, the ad server may compare a returned content type of the advertisement to one or more predetermined Mime-types (e.g., set by the publisher). In various embodiments, the ad server may scan the XML structure for validity. In various embodiments, the ad server may move objects in the XML code around based on a given specification (e.g., VAST 1.0, VAST 2.0, or VAST 3.0) to ensure compliance and maximize the chance of the advertisement rendering at the client device.

In various embodiments, when a noncompliant advertisement is identified, the ad server will select the next highest bid to confirm whether that next highest bid has a compliant advertisement. In various embodiments, when a valid media file is determined to exist, the stored metadata and/or trackers from the bidder (e.g., DSP, SSP, and/or exhange) may be inserted back into the inline document (e.g., XML document). In various embodiments, the ad server may insert its own metadata and/or trackers into the inline document. In various embodiments, after the metadata and trackers are inserted back into the inline document, the asset is returned to the client device for rendering.
